摘要：The structure of posttraumatic stress disorder (PTSD) symptoms has been studied and discussed since the introduction of PTSD as a diagnostic entity in the DSM-III (Diagnostic and Statistical Manual of Mental Disorders III) in 1980.Many studies supported a four-factor or a five-fac_tor models,both inconsistent with DSM-IV.It is unclear whether current DSM-5 criteria appropriately reflect the empirical structure of PTSD symptoms.participants and procedure In this study the structure of PTSD symptoms was exam?ined by confirmatory factor analysis conducted on the data obtained from 388 individuals (150 males and 239 fe?males aged 18-83) who experienced a traumatic event and completed the PDS-5 (Posttraumatic Diagnostic Scale-5),a self-report scale according to the DSM-5 criteria.results Fitting of different models based on DSM-IV,DSM-5 and other the most common four- and five-factor conceptual?izations of PTSD symptoms structure was examined.The data analyses demonstrated the best fit of the six-factor model based on the conceptualization of Elhai et al.(2011) with the additional factor of negative cognitions and mood.conclusions The DSM-5 diagnostic criteria do not reflect the empiri?cal PTSD symptom structure.The data suggest also that it is reasonable to separate the core PTSD symptoms from broad PTSD symptomatology.
